Does anyone have the source for the La Fente, France birthplace?
Coertzen has it as the Thimerais region in France - which he places with a question mark in Normandie. Google maps superimposed on a map of the time suggests Thimerais might have been in the Ill-de-France region closer to Paris, although next to Normandy.
The mystery would be solved if La Fente were somewhere there, but it appears that it is in the S of France.
